Abstract: A method of operation of pump-ejection well pulse unit includes supply of active liquid medium by string of pump-compressor pipes (PCP) to the jet of jet apparatus and pump-out by jet apparatus from stratal zone, through PCP string, of passive medium. Before those operations by means of blocking insert installed in the PCP string one closes the channels of supply of both media to the jet apparatus, with bringing the packer to transportation condition, and with processing by means of hydro-pulse unit of well bottom under-packer zone with active medium, with discharge through the packer of part of medium from the well to surface. After the end of that operation one brings packer to working position and changes the blocking insert to depression insert with insulating one from another the channels of supply of active and passive media to the jet apparatus. Pump-out of passive medium is performed through the system of back peripheral valves installed on the PCP string lower than the packer. Before feeding to hydro-pulse unit medium goes through fine purification filter. As hydro-pulse unit one uses the main and connected to it pre-switched cavitators installed lower than perforation of well bottom zone. The main cavitator forms quick pressure flow, and the pre-switched cavitator forms the zone of secondary cavitation. Working liquid is preliminarily filtered through the raw purification filter, it goes through aerator, this through back valve is connected to compressor or tank with compressed gas (nitrogen, CO2), and is directed through swivel to PCP, and discharge of working liquid from the well is performed through safety valve placed at the discharge line.
